A new flexible PR domain model to replace the fixed multi-PR region model for DPR systems

Abstract

Currently Xilinxpsilas dynamic partial reconfiguration (DPR) model requires the size and number of partially reconfigurable (PR) regions to be fixed during the design phase. Only one PR module may be active per PR region at any given time. This paper presents a new DPR model that replaces the current multi-PR region model with a single partially reconfigurable domain (PR Domain). Multiple PR modules of different sizes are able to concurrently reside in the PR domain. PR modules may be loaded to any portion of the PR domain given that sufficient resources exist. Future PR modules can be designed with dimensions up to those of the PR domain. A case study with multiple PR modules of varied sizes is used to demonstrate the adaptability and flexibility of the PR domain model.
